Various HDL (Verilog) IP Cores

Audio controller (I2S, SPDIF, DAC)

Converts I2S to TDA1540 input format

I2S (Inter-IC Sound) interface module with APB (Advanced Peripheral Bus) interface signals. It has control logic for writing and reading data to/from a 4x32-bit FIFO and generates clock (sck), word select (ws), and serial data (sd) signals for I2S transmission.

A real-time audio visualizer on an FPGA. Receives and transmits audio packets via I2S, and displays the time-domain waveform of the input signal using VGA. Supports changing waveform and background colours via UART.

SONEO is an SR2CB application for digital audio distribution
